Subject: stats: Limit reporting by class id

This commit adds class_id fields to the rate_ctr and stat_item group
descriptions. The stats reporter code is extended to only process
groups whose class_id does not exceed a per reporter max_class level.

If the class_id is not set, the code assumes 'global' for groups with
idx == 0 and 'subscriber' otherwise.

The following vty command is added to config-stats:

  level (global|peer|subscriber)  Set the maximum group level
